String matching algorithms are used in finding a pattern in a string. In this paper, the authors have given a novel algorithm to reduce the time complexity of string matching. The proposed algorithm is based on the concept of hashing with chaining. Further, the authors have found reduced time...
In contrast to this theorem, standard string matching can be performed on the RAM model using time T and space S satisfying TS = O(m) =-=[5]-=-. 4 Conclusions For the standard p-string matching problem, we have derived an algorithm whose complexity is independent of j\Sigmaj, the ...
Merge Sort Algorithm is considered as one of the best sorting algorithms having a worst case and best case time complexity of O(N*Log(N)), this is the reason that generally we prefer to merge sort over quicksort as quick sort does have a worst-case time complexity of O(N*N)...
SEMO only flips one bit in each mutation, and previous work avoided the complexity of analysing standard mutations. Theorem 8 The expected time for QD, operating on the 1-NoO feature space, on OneMax to cover all [Math Processing Error]n+1 cells equals the expected time of GSEMO covering...
It relies on a tree structure and a more complex prediction algorithm to offer considerably more accurate predictions than many state-of-the-art pre- diction models. However, an important limitation of CPT is its high time and space complexity. In this article, we address this issue by ...
We observe that in Lemma 2.1 the nτ-factor in the time complexity is due to matching X in the sampled suffix tree STi by passing the string τ times, each time with a different choice of j∈[1,τ], j≠i. Each such pass costs us O(nlognτ) time. The idea is to reduce th...

RE2 is a regular expression engine designed to operate in time proportional to the size of the input, ensuring linear time complexity. RE2JS, on the other hand, is a pure JavaScript port of the RE2 library— more specifically, it's a port of the RE2/J library....
